SPRING APPLIANCE FOR HARNESS.

SPECIFICATION forming part of Letters Patent No. 457,156, dated August4, 1891.

Application filed October 20, 1890. Serial No. 368,766. (No model.)Patented in England September 17, 1889, No. 14,622-

To all whom it may concern: I

Be it known that I, CLEMENT ARTHUR HILL, a citizen of England, residingat Sheifield, in the county of York,En gland,haveinvented certain newand useful Improvements in Spring Appliances forHarness, Road, and otherVehicles, and for other purposes, (and for which I have obtained apatent in Great Britain, No. 14,622, dated September 17, 1889;) and I doherebydeclare the following to be afull, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to a spring appliance for harness in which thereis combined with two draw-rods a longitudinally-slotted frame withinwhich they work, a spring wound on said frame and passing at one endthrough a slot in the latter, the said spring connecting said draw-rodsand frame, and the motion of the said draw-rods in either directionbeing resisted by elastic connection with said frame.

In the accompanying drawings, Figure 1 represents a side elevation ofthe devices embodying my invention. Fig. 2 represents in detail theslotted tubular frame. Fig. 3 represents in detail the collar anddraw-bar, and Fig. 4 represents a modification of Fig. 1.

A and A represent the draw-rods provided with holes and slots. Theserods are also each provided at one end with an eye,hook, or swivelattachmentto receive the harness connections.

B is the tubular frame, slotted at D and D to allow spring C to passthrough the rods A and A, also to allow motion of said spring. Saidframe B is also provided with holes to receive the pins which secure thecollars E and F upon its ends. These collars E and F are provided withholes for securing them and act as stops, against which the ends ofspring 0 are compressed.

The draw-rods A and A lit within the tubular frame B and are heldnormally so by spring 0, which passes around frame B on its outersurface and then through slots D and D and the holes in the ends of saiddraw-rods. This will constitute the extension part of my device. Thespring 0, after passing through the holes in rods A and A, passes outthrough away with these collars by turning the ends of the spring 0 inthrough additional slots cut in frame B and the draw-rods A and A, theouter ends of the slots inthe frame B acting as the stops, the ends ofthe spring C working freely in the slots in the draw-rods.

This invention may be used on any chain, rope or the like, where it isdesirable to break any sudden shock or strain.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In combination with two draw-rods and a longitudinallyslotted framewithin which they work, a spring wound on said frame and passing at oneend through a slot in the latter, the said spring connecting saiddraw-rods and frame, and the motion of the said drawrods in eitherdirection being resisted by elastic connections with said frame,substantially as set forth. I

2. In combination with a slotted tube, a spring Wound thereon andpassing at one end through a slot therein, and draw-rodsworking withinsaid tube and having the said spring attached thereto, the arrangementof the latter being such that a part will be compressed while a part isexpanded by the same motion of the draw-bars, so as to constitute, ineffect, two springs of reverse action, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.I

CLEMENT ARTHUR HILL.
